STEAM-CONDENSING MEANS.

Application led September 19, 1925.` Serial No. 57,298.

The object of my invention is to aiiord simple, inexpensive, but etective means whereby steam may be quickly and conveniently condensed and disposed o't' as required, as for instance,l in the condensation ot' exhaust steam from steam engines, or for analogous purposes; and to this end the invention consists essentially in the specific comliiination, construction and arrangement oit parts and elements described and claimed herein,a distinctive feature being the injection ot the steam through contractive nozzles into a plurality ot condensing tubes in such manner as to create a partial vacuum therein, whereby expansion of the steam and rapid condensation thereof is attained, all as hereinafter fully set forth.

In the acconipanying drawing;l lf illustrate, more or less diagran'nnatially, a practical embodiment ot the essential features ot my invention.

lVith this understanding the drawing referred to may be designated as a vertical sectional elevation of my new type ot' steam condenser, interposed between a source ot steam supply, as ior instance the cylinder head oi? a steam engine, E, and a reservoir R, it'or the recept-ion of the water ot condensation, both ot which elements are represented symbolically in said drawing.

Thus, the pipe c, from the engine E. conducts the exhaust steam thereiron'i to the inlet or exhaust steam chest S, of the condenser, as considered in a unitary sense, and the pipe fao, conducts the water ot' condensation from the reception chamber TV, to the reservoir R, or to other repository.

interposed between and connected with the said exhaust steam chest S, and the said water reception chamber lV, are a. series oi'v condensation tubes C, C, their lower extremities openingfor their full diameter into the water reception chamber TV, but having; their upper extremities closely sealed except onlv for the steam injection nozzles N. N. which protrude into the upper extremities of said condensation tubes C, C, and communicate with the exhaust steam chest S.

The number of injection nozzles N, N, and their combined area ot' discharge, should be proportionate to, and at least equal the area of the exhaust steam pipe c, so as to obviate possibility of back pressure; and said nozzles should be positioned, as shown, each in axial alignment with the central vertical axis ot its condensation tube C. In this connection it may be stated that w', is avent in the water reception chamber lV, to obviate back pressure therein, and in the condensation tubes C, C;

In operation the injection of steam through the nozzles N, N, into the upper portions of the otherwise sealed condensation tubes creates therein a partial vacuum above and adjacent to the discharge oriices of said nozzles, and this reduction ot' initial pressure results in high expansion of the steam and consequent rapidity ot' condensation.

Hence vit is obvious that, aside from the simplicity oi' construction and arrangen'ient of my steam condenser, the distinctive characteristic thereof is the provision ot the injector nozzles in the otherwise sealed upper portions of the condensation tubes, and the method thus involved ot' promoting condensation o't steam by expansion thereof under partial vacuumpin essentially the manner described.` y

'The condensation tubes C, C, externally to Contact with the and cooled thereby.

llihat I claim as my invention and desire to secure by Letters Patent, isz- Steam condensing' means of the character designated, comprising;- an exhaust steam chest, a chamber for the reception of water ot condensation formed with an air vent.y and a plurality ot condensation tubes interposed between said steam chest and said fa ter receptacle and opening into the latter at their lower extremities` the upper extremity ot each condensation tube being sealed as related to the steam chest, and an injection nozzle positioned in the upper portion ot each condensation tube and communicating` with the said steam chest, substantially in the manner and for the purpose set forth.
